Issue:
I've recently started developing (C++) on Win10. I have a CMake project that builds perfectly fine (both debug and release build), however if I try to run it with the intention of debugging, I get VCRUNTIME140_1D.dll missing error.
The issue lies in the absence of the debug version of the VC++ runtime 140.1 (hence the D prefix in the error message).
I start the binary in two ways:
- PowerShell - where it silently crashes (it's a very typical uncooperative behaviour in PowerShell that I still need time to get used to)
- Debugging mode in VS2017 - for the actual debugging. This is where the actual error (in the form of a message box) appears on my screen.
Setup:
Using Visual Studio 2017, Win10. Debugging is required during the development stage but later on a release build will be created and shipped to the customer.
Using CMake 3.12 (shipped with VS2017). Full CMakeLists.txt can be seen at the end.
The libraries I am linking against are
libtorch 1.12.1- latest version of libtorch C++ binaries with dependencies (straight from the official website of PyTorch). Currently unable to identify compiler.opencv 4.6.0- latest version of OpenCV binaries (straight from the official website of OpenCV). Two versions available - VC14 and VC15. Using VC15, assuming that it refers to VC++ shipped with Visual Studio 2015, that is v140/v140.1 of the MSVC toolkit.
Both dependencies are available in debug and release versions. However I would like to (if possible) link against the release versions of the 3rd party libraries and concentrate on debugging my own code (the size of libtorch's debug build is insane - for both CPU and CUDA you get whopping 12GB!).
Ideas:
I looking on my C:\ and all I can find were
vcruntime140d.dllvcruntime140.dllvcruntime140_1.dll
I also read that /MD vs /MDd as flags play an important role.
I've encountered a couple of posts online mentioning that I need to install Visual Studio 2019.
Questions:
Following two questions are important here:
Which components do I need to install (VS2019 or otherwise) in order to obtain just this DLL and is it sufficient to have it in order to be able run in debug mode?
Can I use (for debugging only) a VC++ Runtime shipped with VS2019 Community Edition in a VS2017 Professional Edition project? Currently I have only access to the Pro version of VS2017.
